Robertson in her book ignores any evidence of fraud in the mediums she discusses. She has written that the Irish medium Eileen Garrett communicated with spirits from the R101 airship that crashed, however, this case was debunked by Melvin Harris as a hoax. Robertson does not refer to Harris in her book or bibliography.[2] She also claims other fraudulent mediums such as Leonora Piper and Gladys Osborne Leonard communicated with spirits.

Robertson in her book ignored any critical or skeptical material on the paranormal, and her bibliography consists of only spiritualist books. Skeptical investigator Joe Nickell has debunked many of the alleged apparitional and poltergeist cases that Robertson claims are genuine. Practically everything in the book that Robertson claims is genuine evidence for life after death has been debunked in skeptical literature but Robertson has ignored all of it.

The only supporters of Robertson are other spiritualist cranks such as Michael Prescott and Victor Zammit.[3]
